Thanks a lot always good to have more people who are actively involved.
As you noticed, I m a bit of track in the normal approach.
So if you want to start building I would advice you to start winding a grenade and kacher.
Build some usable electronic boards... like brovin kacher system,  mosfet puls board etc. In order to tune and or run a system.

Yes, Kacher and Grenade is what I'd like to first wind. My knowledge on Kap goes back not nearly as far as y'all who are actively involved although I've done my due diligence and amassed ample research and have rudimentary understanding.

Why aim for 8MHz/37.5m? Is there a reason for 8MHz/37.5m other than easy 1/4 wave and 1/2 wave division?

Your methodology appeals to me, Ape. Solid documentation of real-world ascertained numbers. It seems your track is right on track!

Let me know what configuration you' d like to built

What configuration do you suggest building first?

Hello my gentlemen's,

This year will surely pop some good news in FE alike device, all you geeks on loose are packed with sauce 

Wish you all the very best success and good luck.

So after many tests with inductorcoil I want to rap_up the results.

For good understanding specially to the new people here is that I m trying to get the whole system @ 2.0Mhz.
1/4 wave 2.0Mhz.
When you use a lower frequency you have to adjust the groundline length.... comparingbwith wavelength total.

We want to mix two wave signals into the grenade.
The 1 billion question is  " how"
Dog-one has given a good description regarding impuls effect and how we assume kacher energy pours in.

The shown devices online all use magnetic field by inductorloop, this concept I don't do here.... maybe when this impuls story comes to a deadend.

So back to the bench,..
Creating sharp pulses peneterating grenade can only be done by switching the inductor to ground.
Not in Ruslan vid schematic.

Switching inductor with negative voltage gave the 1kV positive puls with 380 - 1000ns duration. (Depending on induction value inductor)

Each inductor version 9.375 or 12.5m versions required a different puls frequency.... 24- 30 khz  for max Vpiek.

So now comes the question for Dog,
We have a rise and fall time of 100V/ns... with f.i. 500ns delay beteeen both.
We can trigger one kacher cycle.
Crucial is to synchronise both mosfets ( kacher and impuls) as narrow as possible.
I think I purchase the Raspberry today

Then we have the negative wave from kacher.... ot needs to be draind to ground....this subject is important...
Does a drain attempt with a diode trough the groundline effect us somewhere?

Probably impuls voltage needs to be higher.

So what should be the best way forward to do first?
Personally I bet synchronisation first

Where is this 8Mhz coming from that we are basing many these prototypes on?

Is this referenced elsewhere, or is 8Mhz an arbitrary number?

Ovun;

Your asking about the 8mhz well if the wave length is 37.5mtrs then the if the speed of light is 300, million miles
per second and you have a piece    wire that's 35mtrs long then it takes a  frequency of approx 8.57 mhz to bring it into resonance, you do know what resonance is.

Also the grenade has 4 sections in length each section is about 2mhz each to tune a 2mhz wave in each one,
I would presume. look up P Reva if you want to know more  on you tube (HYiQ)
